Description

Technical Field

[0001] This utility model relates to equipment for forming brackets, and more particularly to a production line for forming bracket profiles. Background Technology

[0002] Seismic bracing and greenhouse supports are various components or devices that limit the displacement of auxiliary electromechanical engineering facilities, control the vibration of these facilities, and transfer loads to the load-bearing structure. During an earthquake, the supports should provide reliable protection for the building's electromechanical engineering facilities and withstand seismic forces from any horizontal direction. Channel steel is a long strip of steel with a U-shaped cross-section. It belongs to carbon structural steel for construction and machinery and is a complex-section steel material with a U-shaped cross-section.

[0003] For the cross-section of the channel steel profile used in the existing support structure, please refer to [reference needed]. Figure 11 The forming process of sheet metal using cold bending technology includes: first, forming the small edge → then forming the flange → finally forming the upright edge → shaping. Traditional production lines can meet the forming requirements of this type of profile, but generally, a production line can only process one specification of profile. However, the actual required profiles have multiple specifications, see [link to relevant documentation]. Figure 12 As shown, the small edge, flange, and top edge are identical across various specifications, differing only in the height of the vertical edges. Traditional production lines require adjustments to the width and height of the pressure rollers when processing other profile specifications, leading to cumbersome equipment adjustments and low processing efficiency. Therefore, there is an urgent need for a forming production line suitable for processing channel profiles with varying vertical edge heights. Summary of the Invention

Detailed Implementation

[0039] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0040] like Figure 1 As shown, the bracket profile forming production line includes a small edge forming mechanism 100, a flanging forming mechanism 200, a standing edge forming mechanism 300, and a shaping mechanism 400 arranged sequentially along the material movement direction. The small edge forming mechanism 100 bends the two ends of the unwound material to form small edges, that is... Figure 10 In the first step of the process, the small edge is formed. The flanging forming mechanism 200 further bends the sheet material after the small edge is formed to form a flanged edge. Figure 10 In the second step of the process, the flanging forming mechanism 300 further bends the flanged sheet material to form a vertical edge. Figure 10 The third step, edge forming, involves the shaping mechanism 400 used to shape the profile after edge forming. Figure 10The fourth step is shaping. After the profiles are shaped, they are cut and then stacked for output.

[0041] Figure 9 shows the processing steps for two different profile specifications. Due to the different heights of the vertical edges, the positions of the left and right forming rollers need to be adjusted to increase or decrease the distance between the two forming rollers during the first step of small edge forming and the second step of flanging forming. However, during the third step of vertical edge forming, the position of the top edge remains unchanged, so the position of the forming rollers does not need to be changed. During the fourth step of shaping, the position between the upper and lower forming rollers needs to be adjusted because the heights of the vertical edges are different.

[0042] The small edge forming mechanism 100 described in this application has the same forming principle and similar structure as the traditional small edge forming mechanism 100. The main difference is that the width can be adjusted in this application. The flanging forming mechanism 200 described in this application has the same forming principle and similar structure as the traditional flanging forming mechanism 200. The main difference is that the width can be adjusted in this application. The standing edge forming mechanism 300 described in this application has the same forming principle and structure as the traditional standing edge forming mechanism 300.

[0043] See Figures 2 to 4 The small edge forming mechanism 100 includes small edge sliding plate frames 101 located on the left and right sides of the plate and a small edge width adjustment drive device that drives the two small edge sliding plate frames 101 to slide inward or outward simultaneously. Several small edge movable pressure roller devices are arranged sequentially between the two small edge sliding plate frames 101 along the moving direction of the plate. This device adjusts the distance between the two small edge sliding plate frames 101 through the small edge width adjustment drive device, thereby driving the left and right forming rollers on them to slide inward or outward simultaneously, reducing or increasing the distance between the two rollers, thus adapting to profiles with different vertical edge specifications.

[0044] The small edge forming mechanism 100 includes multiple small edge width adjustment slide rails 102, which are horizontally and fixedly installed on the top of the small edge roller pressing base 103. Multiple small edge width adjustment slide rail seats 104 are fixedly installed on the bottom of the two small edge sliding plate frames 101 respectively. The small edge width adjustment slide rail seats 104 are slidably installed on the small edge width adjustment slide rails 102. When the small edge sliding plate frame 101 is driven, the small edge width adjustment slide rail seats 104 slide along the small edge width adjustment slide rails 102 to adjust the width.

[0045] The small side width adjustment drive device includes a small side width adjustment reduction motor 105 located in the middle of the lower part of the small side sliding plate frame 101. The front and rear output ends of the small side width adjustment reduction motor 105 are respectively connected to a small side power transmission box 107 through a small side width adjustment transmission shaft 106. The left and right output ends of the small side power transmission box 107 are respectively fixedly connected to small side width adjustment drive screws 108. The threads of the two small side width adjustment drive screws 108 are opposite. Small side width adjustment screw nuts 109 are fixedly installed at the bottom ends of the two small side sliding plate frames 101. The small side width adjustment screw nuts 109 are threadedly connected to the small side width adjustment drive screws 108. The small side width adjustment reduction motor 105 and the small side power transmission box 107 are symmetrically arranged between the two small side sliding plate frames 101. The connection positions of the two small side width adjustment drive screws 108 on the same small side power transmission box 107 and the corresponding small side width adjustment screw nuts 109 are symmetrical, so that the resistance of the two small side sliding plate frames 101 acting on the two small side width adjustment drive screws 108 is basically the same, and the equipment can achieve good balance during and after the width adjustment process. The bottom ends of the small side width adjustment reduction motor 105 and the small side power transmission box 107 are fixed on the small side roller pressing base 103.

[0046] The small-edge movable pressure roller device includes an upper and lower adjustable small-edge pressure roller assembly, and a board movement channel is formed between the upper and lower adjustable small-edge pressure roller assemblies. The small-edge adjustable pressure roller assembly includes a small-edge roller pressure shaft 110 and a small-edge roller pressure shaft sleeve 111. The left end of the small-edge roller pressure shaft 110 is connected to the left side small-edge sliding plate frame 101, and the right end of the small-edge roller pressure shaft sleeve 111 is connected to the right side small-edge sliding plate frame 101. The right end of the small-edge roller pressure shaft 110 is slidably installed through the inner circumference of the small-edge roller pressure shaft sleeve 111. Small-edge forming pressure rollers 112 are respectively fixed on the small-edge roller pressure shaft 110 and the small-edge roller pressure shaft sleeve 111. The left and right small-edge forming pressure rollers 112 are used to bend the ends of the board into small edges. Since the forming technology of small-edge forming is existing technology, the specific structure of the pressure rollers will not be described in detail here. Since the small side roller pressure shaft 110 and the small side roller pressure shaft sleeve 111 can only slide axially and cannot rotate relative to each other, and the right end of the small side roller pressure shaft 110 is fitted inside the small side roller pressure shaft sleeve 111 and extends outside the right end of the small side roller pressure shaft sleeve 111, a cantilever configuration is not formed, making the installation method more reliable. At the same time, when the width is adjusted, the two small side forming pressure rollers 112 installed on the two small side sliding plate frames 101 also slide inward or outward accordingly. Therefore, the positions of the unwinding machine and the cutting machine do not need to be adjusted in the left and right directions, and the usage requirements can be met.

[0047] The upper and lower small side rollers 110 can transmit power through gears. Each lower small side roller 110 has a transmission box connected to one end. The transmission boxes are connected to a drive motor, which controls the rotation of the rollers. The motors and transmission boxes used to drive the small side rollers 110 are all mounted on the sliding small side sliding plate frame 101, ensuring that the power between the rollers and the small side rollers 110 is continuous and unaffected by width adjustment.

[0048] In this device, both of the small-side sliding plate frames 101 are slidable. When adjusting the width, they can slide inward or outward simultaneously, which can reduce the travel of the plate frame on one side and avoid the situation where one side has a large amount of unused space. Furthermore, since the two small-side sliding plate frames 101 slide relative to each other from left to right, the device as a whole remains symmetrical about left and right after the width is adjusted. The center of the device does not shift, which not only improves the overall aesthetics but also ensures that the stability of the device is not affected, thus maintaining the position of other processing mechanisms.

[0049] Once the width adjustment is complete, the small side width adjustment drive device stops moving, and the lower ends of the two small side sliding plate frames 101 are locked by the small side width adjustment drive device. In order to improve the positional accuracy between the two small side sliding plate frames 101, a screw can be provided at the top of the two small side sliding plate frames 101. The screw and the small side sliding plate frame 101 are locked and fixed by using a locking nut. It cooperates with the locking device below to accurately fix the position of the two small side sliding plate frames 101.

[0050] Since the structure of the flanging forming mechanism 200 is basically similar to that of the small edge forming mechanism 100, the main difference lies in the number of flanging movable pressure roller devices and the structure of the flanging forming pressure roller, therefore the accompanying drawings are omitted.

[0051] The flanging forming mechanism 200 includes flanging sliding plates located on the left and right sides of the sheet metal and a flanging width adjustment drive device that drives the two flanging sliding plates to slide inward or outward simultaneously. Several flanging movable pressure roller devices are arranged sequentially between the two flanging sliding plates along the moving direction of the sheet metal. This device adjusts the distance between the two flanging sliding plates through the flanging width adjustment drive device, thereby driving the left and right forming rollers on them to slide inward or outward simultaneously, reducing or increasing the distance between the two rollers, thus adapting to profiles with different vertical edge specifications.

[0052] The flanging forming mechanism 200 includes multiple flanging width adjustment slide rails, which are fixedly installed across the top of the flanging roller pressing base. Multiple flanging width adjustment slide rail seats are fixedly installed at the bottom of the two flanging sliding plate frames, and the flanging width adjustment slide rail seats are slidably installed on the flanging width adjustment slide rails. When the flanging sliding plate frame is driven, the flanging width adjustment slide rail seats slide along the flanging width adjustment slide rails to adjust the width.

[0053] The flanging width adjustment drive device includes a flanging width adjustment reduction motor located in the middle below the flanging sliding plate frame. The front and rear output ends of the flanging width adjustment reduction motor are respectively connected to a flanging power transmission box via a flanging width adjustment transmission shaft. The left and right output ends of the flanging power transmission box are respectively fixedly connected to flanging width adjustment drive screws. The threads of the two flanging width adjustment drive screws have opposite directions. Flanging width adjustment screw nuts are fixedly installed at the bottom ends of the two flanging sliding plates, and the flanging width adjustment screw nuts are threaded to the flanging width adjustment drive screws. The flanging width adjustment reduction motor and the flanging power transmission box are symmetrically arranged between the two flanging sliding plates. The connection positions of the two flanging width adjustment drive screws and the corresponding flanging width adjustment screw nuts on the same flanging power transmission box are symmetrical, so that the resistance of the two flanging sliding plates acting on the two flanging width adjustment drive screws is basically the same, and the equipment can achieve good balance during and after the width adjustment process. The bottom ends of the flange width adjustment reduction motor and the flange power transmission box are both fixed on the flange roller base.

[0054] The flanging movable pressure roller device includes upper and lower adjustable flanging pressure roller assemblies, with a board movement channel formed between the upper and lower adjustable flanging pressure roller assemblies; the adjustable flanging pressure roller assembly includes a flanging roller pressure shaft and a flanging roller pressure shaft sleeve, the left end of the flanging roller pressure shaft is connected to the left flanging sliding plate frame, and the right end of the flanging roller pressure shaft sleeve is connected to the right flanging sliding plate frame. The right end of the flanging roller pressure shaft is slidably installed through the inner circumference of the flanging roller pressure shaft sleeve. Flanging forming pressure rollers are respectively fixed on the flanging roller pressure shaft and the flanging roller pressure shaft sleeve. The left and right flanging forming pressure rollers are used to bend the ends of the board into a flanged shape. Since the flanging forming technology is existing technology, the specific structure of the pressure rollers will not be described in detail here. Since the flanging roller and the flanging roller sleeve are slidably connected, the right end of the flanging roller is fitted inside the flanging roller sleeve and extends outside the right end of the flanging roller sleeve, thus avoiding a cantilever configuration and making the installation more reliable. Simultaneously, when the width is adjusted, the two flanging forming rollers mounted on the two flanging sliding plate frames also slide inward or outward accordingly. Therefore, the positions of the unwinding machine and the cutting machine do not need to be adjusted left or right, meeting the usage requirements.

[0055] Power is transmitted between the upper and lower flanging rollers via gears. One end of each lower flanging roller is connected to a transmission box, which is connected to a drive motor to control the rotation of the rollers. The motors and transmission boxes used to drive the flanging rollers are all mounted on a sliding flanging plate frame, ensuring that the power between the rollers and the flanging rollers is continuous and unaffected by width adjustment.

[0056] Once the width adjustment is complete, the flange width adjustment drive device stops moving, and the lower ends of the two flange sliding plates are locked by the flange width adjustment drive device. In order to improve the positional accuracy between the two flange sliding plates, a screw can be provided at the top of the two flange sliding plates. The screw and flange sliding plates are locked and fixed by a locking nut. It works in conjunction with the locking device below to accurately fix the position of the two flange sliding plates.

[0057] See Figure 5 The edge-forming mechanism 300 includes edge-fixing frames 301 located on the left and right sides of the sheet metal. A plurality of edge-pressing roller devices are sequentially arranged between the two edge-fixing frames 301 along the direction of sheet metal movement. Each edge-pressing roller device includes an upper edge-pressing roller shaft 302 and a lower edge-pressing roller shaft 303 rotatably mounted on the edge-fixing frames 301. An upper edge-pressing roller 304 and a lower edge-pressing roller 305 are respectively mounted on the upper edge-pressing roller shaft 302 and the lower edge-pressing roller shaft 303. Edge-forming is achieved through the cooperation of the upper edge-pressing roller 304 and the lower edge-pressing roller 305. The edge-forming mechanism 300 adopts a conventional structure and is existing technology, which will not be described in detail here.

[0058] See Figures 6 to 8 The shaping mechanism 400 includes shaping frame frames 401 located on the left and right sides of the sheet material. Between the two shaping frame frames 401, an upper limit roller 402, a lower adjusting roller 403, a left vertical roller 404, and a right vertical roller 405 are provided on the top, bottom, left, and right sides of the profile. The lower adjusting roller 403 is raised and lowered by a lifting device to adjust its height relative to the upper limit roller 402. The rotation axes of the upper limit roller 402 and the lower adjusting roller 403 are horizontal, and they are used to abut against the top and bottom edges of the profile, respectively. The rotation axes of the left vertical roller 404 and the right vertical roller 405 are vertical, and they are used to abut against the left and right vertical edges of the profile, respectively. The upper limit roller 402, the lower adjusting roller 403, the left vertical roller 404, and the right vertical roller 405 cooperate to compress and limit the four sides of the profile, achieving the purpose of shaping the profile. In order to accommodate profiles with different vertical edge heights, this application keeps the position of the upper limit roller 402 unchanged and adjusts the distance relative to the upper limit roller 402 by adjusting the position of the lower adjustment roller 403 to process profiles with different vertical edge heights.

[0059] The upper limit roller 402 is fixedly installed on the upper roller pressure shaft 406. Upper connecting blocks 407 are respectively provided at both ends of the upper roller pressure shaft 406. The upper roller pressure shaft 406 is rotatably connected to the upper connecting blocks 407 via bearings. The two upper connecting blocks 407 are fixed to the two shaping plate frames 401. Here, the upper connecting blocks 407 can be directly fixed to the shaping plate frame 401, or indirectly fixed to the shaping plate frame 401 via screws. The lower adjusting roller 403 is located between the left vertical roller 404 and the right vertical roller 405. The lower adjusting roller 403 is installed... Mounted on the lower roller pressure shaft 408, the lower roller pressure shaft 408 has lower connecting blocks 409 at both ends. The lower roller pressure shaft 408 is rotatably connected to the lower connecting blocks 409 through bearings. The two lower connecting blocks 409 are slidably connected to the two shaping plate frames 401. The shaping plate frame 401 is provided with a lifting slide. The lower connecting blocks 409 are limited and slidably installed in the lifting slide. The two lower connecting blocks 409 are controlled to lift and lower through the vertical lifting device, driving the lower adjusting roller 403 to slide up and down between the roller surfaces of the left vertical roller 404 and the right vertical roller 405.

[0060] The vertical lifting device includes two worm gear lifters 410. The housing of each worm gear lifter 410 is fixedly installed. The lifting screw 411 of each worm gear lifter 410 faces upward and is rotatably connected to a flange 412 at its end. The flange 412 is connected to the bottom end of the lower connecting block 409 and can be fixedly supported to the bottom end of the lower connecting block 409 by bolts. The input shafts of the two worm gear lifters 410 are poweredly connected through a synchronous shaft 413. The other end of the input shaft of one of the worm gear lifters 410 is also connected to a height adjustment reduction motor 414. The synchronous shaft 413 ensures that the two worm gear lifters 410 operate synchronously. This device uses the lifting screw 411 of the worm gear jack 410 to support and fix the lower connecting block 409. This bottom-up support and fixing method means that even if the lifting screw 411 fails, it can only slide down and disengage, which will not damage the profile. Compared with the adjustment method located above, this bottom adjustment method makes the equipment safer to use.

[0061] The left vertical roller 404 is connected to the left roller pressure shaft via a bearing, and the left roller pressure shaft is fixed to the forming plate frame 401 via a left bracket; the right vertical roller 405 is connected to the right roller pressure shaft via a bearing, and the right roller pressure shaft is fixed to the forming plate frame 401 via a right bracket. The positions of the left vertical roller 404 and the right vertical roller 405 remain unchanged, and the distance between the two roller surfaces is equal to the distance between the left and right vertical edges of the profile.

[0062] The roller surfaces of the left vertical roller 404 and the right vertical roller 405 are vertically positioned to contact the left and right vertical edges, and the height of the roller surfaces is greater than the vertical adjustment area of ​​the lower adjusting roller 403, making them suitable for profiles with various vertical edge heights.

[0063] The upper limit roller 402 and the lower adjustment roller 403 are both horizontal.

[0064] This device is used to shape profiles once. When multiple shaping is required, multiple devices can be arranged in sequence along the direction of profile movement.

[0065] The working principle of the plastic surgery mechanism 400 is as follows:

[0066] This device is installed in a forming production line after cold bending and before cutting for profile shaping. The profile is driven backward by several cold bending forming rollers to enter this device. The left vertical roller 404 and right vertical roller 405 respectively squeeze the left and right vertical edges of the profile, while the upper limit roller 402 squeezes the top edge of the profile. The middle of the top edge of the profile contacts and abuts against the roller surface of the upper limit roller 402. The lower adjusting roller 403 squeezes the left and right bottom edges of the profile. During the squeezing process, the bottom edges cause the left and right vertical edges to shift upward, that is, the left and right sides of the top edge are lifted upward until the left and right sides of the top edge are completely in contact with the roller surface of the upper limit roller 402 and then stop. Since the upper limit roller 402 is horizontal at this time, the left and right sides of the top edge can also be made nearly horizontal. For the structural principle, see [link to structural principle]. Figure 9 ;

[0067] When it is necessary to process profiles with different vertical edge heights, the power motor is controlled to make the lifting screw 411 of the worm gear lift 410 rise and fall. The lower adjusting roller 403 is raised and lowered through the lower connecting block 409 to adjust the distance relative to the upper limit roller 402. During the adjustment process, the left vertical roller 404 and the right vertical roller 405 remain stationary, and before and after the adjustment, the left vertical roller 404 and the right vertical roller 405 can limit and shape the left and right vertical edges.

[0068] The shaping production line is also equipped with a controller. Different specifications of required vertical edge height can be input into the controller. The controller directly controls the small edge width adjustment reduction motor 105 to automatically adjust the width, the flanging edge width adjustment reduction motor to automatically adjust the width, and the height adjustment reduction motor 414 to automatically adjust the height. Then, the equipment can be debugged, which can greatly improve the processing efficiency of the production line.
